See GNU Parallel live at FSCONS 2010-11-07: http://www.fscons.org/fs/gnu-parallel

Untested Debian and xUbuntu packages available through OpenSUSE build service: https://build.opensuse.org/package/show?package=parallel&project=home%3Atange

Using --retries a job will be retried on another computer if it fails. This is useful if some jobs fail for no apparent reason (such as network failure).

BSD xargs -o (open /dev/tty) is now default for the job running in foreground. Useful for interactive commands like: ls | parallel -Xuj1 vi

GNU sql now supports SQLite.

Renamed .dburl.aliases to .sql/aliases and /etc/sql/aliases.

GNU sql now support --list-tables

Alias for DBURL can contain '?query' part with %-quoting.

About GNU Parallel

GNU Parallel is a shell tool for executing jobs in parallel using one or more machines. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables.

If you use xargs today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. If you use ppss or pexec you will find GNU Parallel will often make the command easier to read.

GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.
